Class and Functional Components

React allows us to make components using both classes and functions. Before React’s Hooks API, only class components could have a state. However, now we can add a state to function components as well. Let’s look at both components, one at a time.

Class components are also called stateful components because they implement logic and state. They also have support for component life cycle methods. The code snippet below shows how a class component is used with React Native.
